Got the lawn mower out the shed for the first time this year, managed to cut the front garden but tried the back and it keeps cutting out...

Any ideas ??? it fires up but than stalls after about 5 seconds

fatherpierre

Fuel starvation or crap in the tank?

Did you drain it dry last the last time you used it??

GlesgaKiss

Could try cleaning spark plug first.

grovesy

Nah didnt drain it last year, plug looks ok.....

was gonna change it but every thing is closed today : (

how do i get the old fuel out ???

fatherpierre

The tank should just be bolted on.

The petrol from last year will have degraded a bit, probably.

Had the same with mine last week as I forgot to let it run dry last year.

grovesy

i will whip the tank off then, do they have any filters ??? its not mine its me GF's and I havent got any tool here so havent had a proper look

fatherpierre

No idea re filters.

I took my tank off, drained the old petrol and the cleaned mine out using a bit of fresh unleaded. Sorted after that.

Check your MAF sensor and get some optimax in there with a splash of octane booster.
Have a look to make sure your wastegate is opening and closing freely, and maybe replace your VTA dumpvalve with an OEM one. If that doenst get her going, give Andy F or Bob Rawle a shout - it may need a remap.

I don't know what it is with petrol these days. I have to drain the tank and clean out the float chamber/jet every year on the mower and then refill with fresh out of a sealed can (well, last year's petrol, but its from a sealed container, so is still fresh).

4 years ago I could use just drag it out the shed and fire it up no worries. Nowadays it refuses to run properly on anything but fresh fuel after being left standing over winter.

RD500 has the same issue

Did you disconnect the Crank Sensor after the last Oil change on it?

Wilky_Boy

Maybe the slow running jet on the carb ? I'd give it a good clean out. What sort of mower is it mate ?

Leslie

Does it run on petrol/oil mix? If the carb was left with fuel in it at the end of the season, the petrol evaporates and the carb jets can get blocked by the oil which is left. I always switch the fuel off and let the engine run to drain the carb when it is stopped for the last time in the year.

Mine started after just a couple of pulls having just left it in the shed all winter with fuel in. Sounds like you lot have temperamental mowers

TopBanana

If it was running fine last year it's going to be bad fuel or a gummed up carb, or both.

You probably need to strip with carb down and get to work with some carb cleaner.

Did my first mow of the year recently - I think I must have pulled the starter cord over 30 times - then it fired up and was fine! Knackered my shoulder though!

I would think that; but after draining the float chamber and filling with fresh fuel and priming it, it always starts first pull. And from that point onwards always starts first pull for the rest of the year.

Its just the first start every year it just doesn't want to know; maybe after enough pulls it would eventually fire, but my limit is five pulls and its out with the spanner to sniff the spark plug Nowadays I don't even do that; I just drain out the fuel tank and float chamber and refill it.

Matteeboy

My strimmer started on the 2nd pull after 4 months non use. Good old Stihl..!

TopBanana

My Stihl chainsaw wouldn't start for love nor money the other day. Turned out the air filter was clogged with the resin of its fallen victims.

Matteeboy

Fallen victims - great line!

Oddly my mower (Husqvarna with a Honda engine) used to start very easily and the strimmer used to be hard work - it's now the other way around.

grovesy

Stripped it down dumped the old fuel from the tank. CLeaned the plug soaked the filter with fresh Fuel and filled up with new stuff. Took a few attempts to start but once it got going no more problems. Starts now with out having to prime...

CHeers for the help

notaclue

keep starting thro the winter then theres no surprises.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^
The username says it all, good advice mate. Not that helpfull...maybe for next year

r32

Try to run the carb dry before parking it up, the fuel evaporating from the float chamber can lead to it gumming up.

But seeing as you've sorted it, happy mowing.......

Snap!
